Acording to my experience, POV-Ray normaly use the background, and any
background feature like a sky_sphere, when evaluating radiosity.
Look at the attached image from a short code contest. The sky is background{rgb
<.5,.7,1>}, the light <8,4,2> and the ground rgb 1 using radiosity with default
settings. You do see bluish areas.
